Guiding device and ultrasound device system

Abstract

A guiding device includes: a guide having a tubular shape. The guide can include a first through hole for insertion of an ultrasound probe. The guide can be configured to guide movement of the ultrasound probe inserted through the first through hole. A protrusion can protrude from one end of the guide and can have a sectional shape that corresponds to a sectional shape of the distal portion of the ultrasound probe, the sectional shape of the protrusion being orthogonal to an axis of the first through hole, and the sectional shape of the distal portion of the ultrasound probe being orthogonal to the axis of the first through hole.

What is claimed is: 
     
         1 . A guiding device comprising:
 a guide having a tubular shape, the guide including a first through hole for insertion of an ultrasound probe that is configured to transmit ultrasound vibration to form a tunnel in a bone using a distal portion of the ultrasound probe, the guide being configured to guide movement of the ultrasound probe inserted through the first through hole; and   a protrusion protruding from one end of the guide, the protrusion having a sectional shape corresponding to a sectional shape of the distal portion of the ultrasound probe, the sectional shape of the protrusion being orthogonal to an axis of the first through hole, and the sectional shape of the distal portion of the ultrasound probe being orthogonal to the axis of the first through hole.   
     
     
         2 . The guiding device according to  claim 1 , wherein the protrusion includes a second through hole configured to receive a miniature drill, the second through hole extending parallel to the first through hole. 
     
     
         3 . The guiding device according to  claim 1 , wherein the guide includes a distal portion cutaway from the one end of the guide obliquely across an axis of the guide. 
     
     
         4 . The guiding device according to  claim 1 , wherein the protrusion includes a proximal end on an outer circumferential face of the guide closer to the one end of the guide. 
     
     
         5 . The guiding device according to  claim 1 , further comprising:
 a rib extending from an outer circumferential face of the guide, wherein   the rib includes a scale that extends in an axial direction of the guide and indicates an entry distance of the distal portion of the ultrasound probe into a bone tunnel.   
     
     
         6 . An ultrasound device system comprising:
 an ultrasound device including an ultrasound probe configured to transmit ultrasound vibration to form a tunnel in a bone with a distal portion of the ultrasound probe; and   a guiding device including:
 a guide having a tubular shape and including a first through hole configured to receive the ultrasound probe, the guide being configured to guide movement of the ultrasound probe; and 
 a protrusion protruding from one end of the guide, the protrusion having a sectional shape corresponding to a sectional shape of the distal portion of the ultrasound probe, the sectional shape of the protrusion being orthogonal to an axis of the first through hole, and the sectional shape of the distal portion of the ultrasound probe being orthogonal to the axis of the first through hole.
